Native Americans in the United States, similar to other indigenous people, created political, economic, and social movements to meet and adjust to major changes that impacted their cultures. For centuries, Native Americans dealt with the onslaught of non-Indian land claims, the appropriation of their homelands, and the destruction of their ways of life. Through various movements, Native Americans accepted, rejected, or accommodated themselves to the nontraditional worldviews of the colonizers and their policies.
